If you’ve watched any television or checked your mail in Texas, you’ve probably seen flashy ads promising "Free Nights!" or "Free Weekends!" from major electricity providers. It sounds too good to be true: turn down your AC all day, run your dryer at midnight, and pay absolutely nothing for your electricity during those periods.
But here is the catch: electricity is never actually free.
While these plans do offer free hours, they charge significantly higher rates during the "non-free" daytime hours. If you don't adjust your lifestyle to fit the schedule, you will end up paying a massive premium.
Key Takeaways
- High Daytime Markup: "Free nights" plans charge double or triple the standard market rate during the day (often 20¢ to 28¢ per kWh).
- The Shift Obligation: To save money, you must shift at least 35% to 40% of your total energy consumption to the designated free hours.
- TDU Delivery Fees: Check the fine print to see if TDU delivery fees still apply to your "free" hours.
- The Lifestyle Tax: These plans penalize families with children, people who work from home, and anyone who runs the AC during the hot Texas afternoon.
How Free Nights & Weekends Plans Work
Free nights and weekends plans are examples of Time-of-Use (TOU) pricing. Instead of charging a flat rate for every kilowatt-hour you consume, the provider divides the day into two categories:
- Free Hours (Off-Peak): Usually 9:00 PM to 6:00 AM, or Friday night to Sunday night. The energy charge is $0.00.
- Paid Hours (On-Peak): All other hours. The energy charge is highly inflated.
In a normal flat-rate plan, you might pay a steady 14¢ per kWh all day long. In a "free nights" plan, you might pay 0¢ per kWh at night, but 25¢ per kWh during the day.
The Math: Why the Math Favors the Provider
Electricity providers have spent millions of dollars analyzing consumer behavior. They know exactly when and how the average home uses power. In Texas, the vast majority of electricity is consumed during the hottest parts of the day—between 1:00 PM and 7:00 PM—when the air conditioner is working overtime to fight the heat.
Here is an interactive comparison detailing the billing math for a home using 1,200 kWh in a month under a standard flat-rate plan vs. a "Free Nights" plan with different levels of usage shifting:
As you can see, if you live normally (70% Day / 30% Night), the "free" plan costs you $42.00 more per month than the flat-rate plan. You only save money if you drastically change your lifestyle and comfort levels to shift more than 35% of your electricity consumption to nighttime.
Hidden Pitfalls of Time-of-Use Plans
1. The Pass-Through TDU Fee
Many providers state that the energy charge is free during the night, but they still pass through the TDU charges (usually 4¢ to 6¢ per kWh) for every kilowatt-hour used during those "free" hours. Check your EFL carefully to make sure "free" actually means zero.
2. The Smart Thermostat Trick
Some plans advertise "Free Smart Thermostat Included!" when you sign up. However, the plan is often locked into a high daytime rate. The free thermostat is paid for by the inflated rate you pay during the day.
3. The Winter Trap
In the winter, heating a home using electric heat pumps can use a massive amount of energy in the early morning hours (6:00 AM to 9:00 AM) right after the "free nights" window closes. This leads to unexpected winter bill spikes.
Should You Sign Up for a Free Nights Plan?
For 90% of Texans, the answer is no. Unless you are away from home all day, work night shifts, or have a large battery backup system (like a Tesla Powerwall) that charges at night and powers your home during the day, a standard fixed-rate plan is always the safer, cheaper choice.
If you are curious whether your home fits a time-of-use plan, GetElectricity can analyze your hourly smart meter history. By mapping your exact historical consumption to the hourly rate structures of these plans, we can tell you exactly what your bill would look like—before you sign the contract.
Run the Free-Nights Math on GetElectricity
As this guide showed, free nights and weekends only pay off when your household can shift a huge share of usage into the free window — and most cannot.
GetElectricity connects directly to your Smart Meter Texas data to build your real 12-month usage profile, then simulates hundreds of active plans across Fort Worth, Waco, Lubbock, and Corpus Christi, comparing time-of-use gimmicks against straightforward fixed rates hour by hour.

What a 35% Shift Actually Looks Like at Home
The table above says you need at least 35% to 40% of consumption inside the free window to break even. On the article's 1,200 kWh month, that means moving 420 to 480 kWh into nights and weekends — roughly a third of everything your home uses. Here is what that takes in practice:
- Air conditioning is the wall. Texas homes burn most of their power between 1:00 PM and 7:00 PM fighting the heat. Precooling the house before the paid window starts helps, but the compressor will still cycle all afternoon — that load alone often exceeds what you can shift.
- The shiftable loads are small. A dryer load is about 3 kWh, a dishwasher run about 1.5 kWh, and a load of laundry in cold water under 1 kWh. Moving all three daily shifts roughly 150 to 180 kWh a month — meaningful, but not 420.
- The big levers are an EV or a pool pump. An EV charged exclusively overnight can add 250 to 400 kWh of shifted load, and a pool pump on a timer adds 100 to 200 kWh. This is why the plan works beautifully for the 10% of households with those loads — and quietly taxes everyone else.
Before signing, pull your smart meter history and compute your real day/night split. GetElectricity maps your hourly intervals onto the plan's windows and prices both structures — if your split cannot beat the 35% threshold, the flat 14¢ rate wins and the "free" plan was never free.
Frequently Asked Questions
How much of my usage do I have to shift to nights for a free-nights plan to save money?
You must shift at least 35% to 40% of your total consumption into the free hours. In the article's 1,200 kWh example against a 14¢ flat-rate plan, an average home running 70% day / 30% night pays $42 more per month on a 25¢-daytime free-nights plan, and even a 60/40 shift still overpays by $12. Savings only appear once nighttime usage reaches roughly half or more of total consumption.
Is the electricity really free during the free hours?
The energy charge drops to $0.00 during the designated off-peak window, but many providers still pass through TDU delivery charges — usually 4¢ to 6¢ per kWh — for every kilowatt-hour used during those free hours. Check the Electricity Facts Label carefully to confirm that free actually means zero.
Who should consider a free nights and weekends plan?
For about 90% of Texans, a standard fixed-rate plan is the safer, cheaper choice. Free-nights plans only fit households that are away from home all day, work night shifts, or own a large battery backup system that charges overnight and powers the home during the day. Watch the winter trap too: electric heat pumps draw heavily from 6:00 to 9:00 AM, right after the free window closes.
